The DIWire Bender is a rapid prototype machine that bends metal
wire to produce 2D or 3D shapes.

Wire unwinds from a spool, passes through a series of wheels that
straighten it, and then feeds through the bending head, which moves
around in 3 dimensions to create the desired bends and curves. Vector
files (e.g., Adobe Illustrator files), text files of commands (e.g.,
feed 50 mm, bend 90° to right…) provide DIWire’s instructions.

It’s essentially a 3D printer that describes lines, instead
of volumes, in space, and it could be used for anything from prototypes
to customized products.
